“ write the equation of the line that goes through the point (6,3) and is parallel to y=-2/3x+5 “ ????

brilliants [131]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{2}{3}$ x + 5 ← is in slope- intercept form

with slope m = - $\frac{2}{3}$

Parallel lines have equal slopes, thus

y = - $\frac{2}{3}$ x + c ← is the partial equation of the line

To find c substitute (6, 3) into the partial equation

3 = - 4 + c ⇒ c = 3 + 4 = 7

y = - $\frac{2}{3}$ x + 7 ← equation of line

If BC = 6 and AD = 5, find DC.<br><br> A) 4<br> B) 4.5<br> C) 7.2

Jlenok [28]

We have three similar triangles, because each has a right angle and shares an angle. Let's write the angles in order: opposite to short leg, long leg, hypotenuse.

CAB similar to BAD similar to CBD

Or as ratios,

CA:AB:CB = BA:AD:BD = CB:BD:CD

We also know

AC = AD + CD

(AD+CD):AB:CB = BA:AD:BD = CB:BD:CD

(AD+CD)/CB=CB/CD

We have CB=6, AD=5 and seek x=CD.

$(5 + x)/6 = 6/x$

$x(x+5) = 36$

$x^2 +5x - 36 = 0$

$(x+9)(x-4) = 0$

We reject the negative root and conclude x=4
